| 摘 要： | 扎合金矿位于准噶尔板块萨吾尔晚古生代岛弧区的中南段,矿体赋存于海西晚期—印支早期侵入的中性闪长岩岩体及围岩接触部位.矿区内发育北西向和北东向两组断裂.北西向断裂既是成矿热液运移的通道,也是金元素富集成矿的场所,岩体为金矿提供了成矿物质和部分热液.根据矿体产出地质特征,扎合金矿属构造蚀变岩型金矿床；据成矿作用分析,该金矿属中低温热液金矿床.

| Abstract: | Zhahe gold deposit is located in the middle-to-south part of the Sawuer late paleozoic island arc of the Junggar plate.Orebodies occurring in diorite invaded the late Hercy-early Indosinian and the surrounding area of diorite.Two groups of faults,i.e.the north-west and north-east faults,exist in the mining area.The north-west faults have been the migration channels of metallogenic hydrotherm and the ore-forming place for the concentration of gold elements.Magma provided the gold metallogenic material and part of hydrotherm. According to the geological characteristics of orebodies,Zhahe gold deposit belongs to the structural alerted-rock type.And a mineralization analysis showed that it is a medium-low temperature hydrothermal deposit. |
